摘　　要：通过研究群速度色散(GVD)和自相位调制(SPM)的相互作用,推导出了速度色散(GVD)和自相位调制(SPM)共同作用所致啁啾的解析表达式.研究结果表明,当色散长度LD和非线性长度LNL确定后啁啾随z和T的变化特性完全确定,随着LD/LNL比率的不同,啁啾特性发生了明显变化,通过控制输入功率可实现无啁啾传输,保持脉冲的稳定性.By taking into account the interactions between SPM and GVD in a singlemode fiber,we obtained an analytic expression of chirp induced by both SPM and GVD chirp.The results show that the feature of chirp according to z and T is determined completely for certain LD and LNL.With different ratio of LD/LNL,the feature of chirp changes obviously.We find that unchirp propagation can be obtained by controlling the input power of pulse in a fiber and the stability of pulse also can be maintained.
